PATRICK W. GORMAN, OF SALT LAKE CITY, UTAH.

SELF-CLOSING FAUCET.

To all whom it may concern:

Be it known that I, PATRICK W. GORMAN, a citizen of the United States,residing at Salt Lake City, in the county of Salt Lake and State ofUtah, have invented a new and useful Improvement in Self-ClosingFaucets, of which the following is a specification.

My invention relates to certain new and useful improvements inself-closing faucets; more especially to a self-closing faucet where aspring is used to operate the movement of the valve to shut ofl' theflow of liquid by spring pressure after the valve stem has been turnedand the valve opened by hand operation.

One object of my invention is to provide a self-closing faucet which canbe readily removed when it leaks or becomes otherwise defective.

Another object of my invention is to provide a self-closing faucet witha means for preventing the liquid from getting into the spring chamber,thus keeping the spring dry and free fro-m rust.

Another object of my invention is to provide a self-closing faucet wherea. disk valve or a plug valve may be used to shut off the flow of liquidby spring pressure.

Another object of my invention is to provide a self-closing faucet inwhich the spring can be removed and the stem packed without thenecessity of taking the faucet all apart, as is customary with all otherself-closing faucets which are in use today.

Another object of my invention is to construct a self-closing faucet inwhich the cap can be removed to repair the spring without taking out thestem.

lVith these and other objects in view, my invention consists of thefollowing novel construction and arrangement of parts, to be hereinafterdescribed and claimed; reference being had to the annexed drawingsforming part of this specification, and to the figures of referencemarked thereon, in which Figure l is a sectional view through line wm ofFig. 2. Fig. 2 is a side elevation showing the cap 35 removed. Fig. 3 isa side view of one of the cylinders 15. Fig. 1 is an end view of Fig. 3.Fig. 5 is a side elevation of the step. Fig. 6 is a sectional plan viewthrough cc of Fig. 1.

Similar letters and numerals refer to like parts throughout the severalviews.

Serial No. 721,697.

A denotes the head of the faucet which has a right-angular projection land a spout 2. The lower portion of the head is threaded at 3 for thepurpose of receiving the thread 4 on the inside of the collar 5. Theshoulder 6 on the upper end of the thimble 7, prevents the collar 5 fromslipping off of the thimble 7 when said collar is screwed onto the head.Located on the inner wall of the thimble 7 are lugs 8 which answer asguides for the valve 9. These lugs form an opening between the valve 9and the inner wall of the thimble 7, this allows the liquid to flowfreely when the valve 9 is pushed down by turning the valve stem 22. Onthe inner wall and at the lower end of the thimble 7 are threads 12 forreceiving the threads 11 on the lug 11 0f the base 10. From the bottomof the base 10 is a threaded projection 13 for screwing into the pipe.

141 is an opening passing through the base 10.

WVithin the right-angular projection 1 are located the cylinder 15 andthe packing 16 and 16. lVithin the cylinder 15 is a coil spring 21encircling the stem 22. Located on the stem 22 are two collars 23 and 21.

and a lug 25. One end of the stem 22 is squared for receiving the handle26, the other end of said stem has a projection 27 forming an eccentricwhich fits into a hole in the upper end of the valve stem 28. Directlyback of the projection 27 are threads 29 for screwing into the hole 30in the wall 17 of the head 1.

The inner end 31 of the cylinder 15 is concaved. A hole 32 runs throughthe center of said concaved end. The hole 32 allows the stem 22 to passthrough. On the outer end of the cylinder are located notches 19 and 20.

On the end of the right-angular projection 1 are threads 33 forreceiving the threads 34 which are on the inner surface of the cap 35.

In assembling my invention, I start with the collar 5 by placing it overthe thimble 7; then I screw the thimble 7 onto the base 10; now I placethe spring 21 around the stem 22, placing one end of said spring intothe hole 30 on the collar 23 of the stem 22; I now place the spring 21and the stem 22 into the cylinder 15; now I insert the washer 16 intothe right-angular projection 1; I then place the cylinder 15, the spring21 and the stem 22 into the right-angular projection 1; now I place thewasher 16 and the cap 35 over the stem 22; I then place on the handle 26and put in the screw 37; now I insert the valve stem 28 into the opening15 of the head A, placing it over the eccentric end 27 of the stem 22;now I screw the threaded end 29 of said stem into the threaded hole 30in the wall 17 or the head A, thus holding the stem 22 firmly in thehead A; now I place the lug 25 into the notch 20 ot the cylinder 15,this lug prevents the handle from tlnning too far around by coming incontact with the notch 20: now I place the end 33 of the coil spring 21into the notch 19 of the cylinder 15 and allow the end of said spring toextend into a notch 38 in the right-angular projection 1; now I screw011 the cap 35. The 'ashers 1t) and 16 are COIHPL'GSSGCl into theirrelative places by the screwing on of the cap I now place a washer 39into the collar now I screw the collar onto the head A by the threads 3,thus completing the'construction of my invention.

In the operation of my invention I apply the power to the handle 26,thus turning the stem 22 which operates the valve 9 by pressing itdownward with the eccentric end 27 until said valve is open. When thesaid valve is open it allows the liquid to flow from the opening it intothe thimble 7, through the grooves d0 which are between the lugs 8, uppast the valve 9, then out through the spout 2, thus completing theoperation of my invention,

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. Self-closing cock comprising incombination, a casing having an inlet provided with a valve seat andalso having a spoutleading therefrom, a valve for said seat, an

extension for said casing having a threaded opening, a cylinder in saidextension provided with an opening registering with the opening in saidextension, a packing dis posed between said cylinder and the wall ofsaid extension, an operating stem extending through the opening in saidcylinder and having threaded engagement with the threaded opening insaid extension and provided with a connection with said valve, means forengaging said cylinder to force the same against said packing, and meansfor returning the stem to a starting position and assisting inmaintaining said cylinder in engagement with said packing, substantiallyas described.

2. A. self closing cock comprising in combination, a casing having aninlet provided with a valve seat and also having a spout leadingtherefrom, a valve for said seat, an extension for said casing having athreaded opening, a cylinder in said extension provided with an openingregistering with the opening in said extension, a packing dis posedbetween said cylinder and the wall of said extension, an operating stemextending through the opening in said cylinder and having threadedengagement with the threaded opening in said extension and provided witha connection with said valve, said stem having a flange engaging saidcylinder to force the same against said packing, and a coil springhaving one end connected with said stem and the other end connected withsaid extension for returning the stem to a starting position andassisting in maintaining said cylinder in engagement with the saidpacking, substantially as described.
